I have a Gionee S Plus, and I installed lately Android 7.1.2 with RR-N-v5.8.5-20171012-A8-Unofficial. Everything is working well (and I thank you for this ROM) except the audio. It has a noticeable bad quality, both on ringtones and music app, comparing to the same phone with Android 6.0. I searched on the net but it didn't find anything relevant. Can anyone help me please?
